What evidence of us will exist in 600 million years? Some of the combusion products of engines are distinct as I understand it, perhaps some materials are stable that long (and if so, they could pose large pollution problems)?
- tabtab 8y agoI'm sure there's plenty of junk in landfills that will make for interesting fossils. The material doesn't have to be "stable", it just has to make an imprint. Most existing fossils don't comprise the original material, but are rather "mineral shadows" of what was there before.
